IMPROVEMENT IN CARPET-CLEANING MACHINES.

Specification formiiag part of Letters Patent No. 132,927, datedNovember 12, 1872.

To all whom it may concern:

Be it known that we, GRANVILLE 0. SMITH and CHARLES T. STORY, of Boston,of the county of Sufl'olk and State of Massachusetts, have invented anew and useful or Improved Machine for Cleansing Carpets; and do herebydeclare the same to be fully described in the following specificationand represented in the accompanying drawing, of which Figure 1 is a topview; Fig 2, a side elevation; Fig. 3, a longitudinal section; and Fig.4, a transverse section of it. Fig. 5 is a flatwise section of itsair-induct and the air regulating and directing guides thereof.

In such drawing, A denotes a hollow drum, arranged to revolve within acylindrical case, B, furnished with an educt, O, as shown. The said casehas two doors, D E, to corresponding openings in its periphery, theybeing arranged, as shown, with reference to the flat air induct F. Thehollow drum has its periphery foraminous, and is provided with openingsthrough one or both ends, the drum being arranged within the caseconcentrically, with its shaft G supported in suitable bearings andextended through one end of such case. The lower door may be furnishedwith counterbalancing weights, connected with cords a a, leading overpulleys b b arranged in the posts 0 c of the frame H, for supporting themachine. Theinductisfurnishedwith an openingthrough its top, and a door,d, thereto, as shown, and the induct at its inner end is to extendnearly if not entirely across the rotary drum, around which and upon itsforaminous periphery a carpet, while being cleansed, is to be stretchedand be held thereon by suitable means. The induct narrows from its frontto its rear end, where it is open to receive the educt of a fanblower orother machine for blowing a powerful blast or current of air into saidinduct. At the inner mouth of the induct is a deflector, I, which ishinged to the mouth. Such deflector may be furnished with a spring forforcing or keeping it down, or upon or nearly in close contact with thecarpet, and it should also have a hand-lever, 0, so connected with itand applied to the induct as to enable such deflector, by means of suchlever and manual power applied thereto, to be raised to differentinclinations, or a horizontal position, as occasion may require, todistribute the blast of air upon the carpet. Within the induct are twomovable wings .or guides, K K, they being arranged as shown, and each ator near its rear end being pivoted to the induct so as to be capable ofbeing swung or movedtoward and from its axis. Each of such wings orguides extends from the top to the bottom of the induct or theair-passage thereof, they being intended to concentrate more or less anddirect upon any part or parts of the carpetexposed to its action thecurrent of air when flowing through the induct.

By means of either or both the guides the current may be made to act allat once upon any portion of the width of the carpet,'or entirely acrossit. The two guides should be provided with means of enabling them oreither of them to be moved within the induct, as occasion may require.Such means may be springs to move them backward, and cords or lines todraw them forward.

With this machine the dust is driven from the carpet by the current ofvair driven through the meshes of the threads, such dust with the airpassing out of the case by the educt, from whence it may be dischargedto a convenient place or reservoir, which may be outside of the buildingin which the machine may be situated. The door openings and doors of thecase are to enable a person to gain access to the foraminous drum forthe purpose of applying and fixing a carpet to it or removing ittherefrom after it may have been cleansed.

We claim- The combination of the induct F and one or more deflectors orguides, I K, applied thereto or arranged therewith, as set forth, withthe foraminous drum A and the case B furnished with an educt 0, allbeing substantially as explained, and to operate as represented.
